They support 10, 100 63ce4946daSBill Paul * and 1000Mbps speeds with 1000baseX (ten bit interface), MII and GMII 64ce4946daSBill Paul * ports. Other features include 8K TX FIFO and 32K RX FIFO, TCP/IP 65ce4946daSBill Paul * hardware checksum offload (IPv4 only), VLAN tagging and filtering, 66ce4946daSBill Paul * priority TX and RX queues, a 2048 bit multicast hash filter, 4 RX pattern 67ce4946daSBill Paul * matching buffers, one perfect address filter buffer and interrupt 68ce4946daSBill Paul * moderation. The 83820 supports both 64-bit and 32-bit addressing 69ce4946daSBill Paul * and data transfers: the 64-bit support can be toggled on or off 70ce4946daSBill Paul * via software. This affects the size of certain fields in the DMA 71ce4946daSBill Paul * descriptors. 72ce4946daSBill Paul * 73cb2f755cSBill Paul * There are two bugs/misfeatures in the 83820/83821 that I have 74cb2f755cSBill Paul * discovered so far: 75cb2f755cSBill Paul * 76cb2f755cSBill Paul * - Receive buffers must be aligned on 64-bit boundaries, which means 77cb2f755cSBill Paul * you must resort to copying data in order to fix up the payload 78cb2f755cSBill Paul * alignment. 79cb2f755cSBill Paul * 80cb2f755cSBill Paul * - In order to transmit jumbo frames larger than 8170 bytes, you have 81cb2f755cSBill Paul * to turn off transmit checksum offloading, because the chip can't 82cb2f755cSBill Paul * compute the checksum on an outgoing frame unless it fits entirely 83cb2f755cSBill Paul * within the TX FIFO, which is only 8192 bytes in size. If you have 84cb2f755cSBill Paul * TX checksum offload enabled and you transmit attempt to transmit a 85cb2f755cSBill Paul * frame larger than 8170 bytes, the transmitter will wedge. 86cb2f755cSBill Paul * 87cb2f755cSBill Paul * To work around the latter problem, TX checksum offload is disabled 88cb2f755cSBill Paul * if the user selects an MTU larger than 8152 (8170 - 18). 89ce4946daSBill Paul */ 90ce4946daSBill Paul 91f0796cd2SGleb Smirnoff #ifdef HAVE_KERNEL_OPTION_HEADERS 92f0796cd2SGleb Smirnoff #include "opt_device_polling.h" 93f0796cd2SGleb Smirnoff #endif 94f0796cd2SGleb Smirnoff 95ce4946daSBill Paul #include <sys/param.h> 96ce4946daSBill Paul #include <sys/systm.h> 97ce4946daSBill Paul #include <sys/sockio.h> 98ce4946daSBill Paul #include <sys/mbuf.h> 99ce4946daSBill Paul #include <sys/malloc.h> 100fe12f24bSPoul-Henning Kamp #include <sys/module.h> 101ce4946daSBill Paul #include <sys/kernel.h> 102ce4946daSBill Paul #include <sys/socket.h> 103ce4946daSBill Paul 104ce4946daSBill Paul #include <net/if.h> 105ce4946daSBill Paul #include <net/if_arp.h> 106ce4946daSBill Paul #include <net/ethernet.h> 107ce4946daSBill Paul #include <net/if_dl.h> 108ce4946daSBill Paul #include <net/if_media.h> 109ce4946daSBill Paul #include <net/if_types.h> 110ce4946daSBill Paul #include <net/if_vlan_var.h> 111ce4946daSBill Paul 112ce4946daSBill Paul #include <net/bpf.h> 113ce4946daSBill Paul 114ce4946daSBill Paul #include <vm/vm.h> /* for vtophys */ 115ce4946daSBill Paul #include <vm/pmap.h> /* for vtophys */ 116ce4946daSBill Paul #include <machine/bus.h> 117ce4946daSBill Paul #include <machine/resource.h> 118ce4946daSBill Paul #include <sys/bus.h> 119ce4946daSBill Paul #include <sys/rman.h> 120ce4946daSBill Paul 121ce4946daSBill Paul #include <dev/mii/mii.h> 122ce4946daSBill Paul #include <dev/mii/miivar.h> 123ce4946daSBill Paul 12438d8c994SWarner Losh #include <dev/pci/pcireg.h> 12538d8c994SWarner Losh #include <dev/pci/pcivar.h> 126ce4946daSBill Paul 127ce4946daSBill Paul #define NGE_USEIOSPACE 128ce4946daSBill Paul 1295da751e4SBill Paul #include <dev/nge/if_ngereg.h> 130ce4946daSBill Paul 131f246e4a1SMatthew N.
